Wet bedroom walls- Condensation?

I could of course take a photo from
the ground on the other side of the road, but it wouldn’t show anything- in terms of damaged / slipped slates.

It should - slipped tiles should be obvious, things like increased spacings etc. There's folks on here who'd know - Stuart, for example?

(I thought that photo was yours at first...)

This is a photo- you can’t see anything from
here I don’t think

Can't see any real signs of nail sickness on your roof. You need to be guided by your roofer. It could be that it's only the eaves that need doing.

I'm not a roofer, Arsenal, tho' I have helped lay a roof in my time.

What I see there does not correspond with what your roofer has said. Of course, I haven't heard everything he did say, but there is no evidence there of 'three rows of slates having slipped'; if you look at the visible heights of the slates - the bits of the slates you can actually see, most of the slate being hidden - they appear to be evenly spaced. A slipped slate would have a lot more of it showing.

Is the bedroom on that RH side? There seems to be a bit more happening on the LH side, above that hopper - some roof sag and unevenness of the slates - but no idea if that's an issue.

I was expecting a party wall to be coming up through your roof separating the houses, and would then have been focusing on the flashing on that, but your roof covering is continuous and looks decent (and quite beautiful).

I wonder if it's water coming around the flashing of that RH stack (with the aerials on it)? That could then trickle down and come through at the bottom when it hits a flat surface.

Sorry - nothing conclusive there.

Did the roofer look inside the roof space? Could he see where the water was landing on your ceiling?

Yes he went up into the attic. He stated that all bottoms rows of the slates were wet\condensated and that he waves were slightly damp too. 

He did also say that the guttering has come away from the wall slightly and that it would just need fixing back to the wall too.

Annoying thing, extremely annoying thing is that it’s looking I can’t claim through my insurance for this.

I'm even more confused now.

Is the issue due to slipped tiles (which I cannot see) or to condensation? If the latter, that is resolved by more ventilation, usually by adding vents or ensuring gaps at the front and back of the roof, usually along the soffits. These are the panels along the bottom of the roof near where the guttering is attached.

I'd assumed he was previously referring to 'slipped' slates - ie slates which have detached from the rafters and have slipped down further towards the guttering, exposing gaps between them. But there is no visible sign of this at all - the roof looks very good. However, I now realise he said 'dropped', and that could mean something different. Does he mean that the bottom rows of slates are lower than they used to be - have sagged - so have cut off what may have been a vent gap along there? I have no idea, but there is no visible sign of that either.

If this is purely a matter of condensation caused by lack of ventilation, then that is usually sorted by adding vent grills to the soffits, front and back. But it begs the question - why would this roof need that all of a sudden - it's been there for many years?

Does your loft trapdoor seal neatly - pretty air-tight? If not, then it could be due to more warm-moist air from your house flowing steadily up there and that COULD condense out more than the ventilation can take care of. That is definitely something to check for FIRST. Photo of your loft hatch, please?! Open and closed.

Failing that, I'm at a loss. It's your call, but based on what the roofer has said - ie nothing that makes sense to me - I would personally not go with him, at least not until he clarifies the situation. What I'd do is call out another roofer, and ask them 3 questions that you must have answers for:

1) What is causing the water up there?

2) How will you sort it?

3) Will it do the trick?

And for each you need an answer that YOU understand. That way hopefully I will too :-)

Well, I initially thought the problem was condensation, because per my picture on the first post, my walls are wet.( only during bad/cold weather). I then got the roofer out to have a look and he stated that it is not condensation. He states that the bottom 3 rows of Slates have dropped. He said that this has left much bigger gaps between the slates, thus letting water/wind in; leading to the wet wall that I have.

Yes, that’s is what I thought. The house had been here for many years and neither neighbour have the issues nowhere near as bad as we do. 

The hatch-door to the loft closes securely too.

I have attached photos of the hatch door below. 

Additionally, I have tried contacting soooo many roofers but it appears as though they cannot be bothered - no ones replying -_-

Ah well - that discounts the leaking loft hatch option... :-(  

Just not convinced by what the roofer says. At the very least, if the lower rows of slates have dropped, I'd like to know why. And wouldn't the simplest solution be to prise the roofing battens up from the rafters and slip a spacer in there? (quite a tight space, tho').

But another concern is, when you looked up there you could see moist/damp on the underside of the slates? I presume all the slates, those immediately above the hatch, those well 'up' from the eaves? So, what's causing that condensation? It's surely not rain being blown in at the bottom.

I cannot see - from your photo - any sign of anything different about these bottom rows of slates; no change of angle, no increase in slate spacing, no larger gaps, nothing.

If the issue is rain being blown in - and perhaps even if it isn't - another solution could be to slip a stiff membrane down the underside of the bottom few rows and out so deflect any rain way and into the gutter. Ie what 'felt' would be doing if fitted. You can get sheet trims for this, or anything else that's thin and waterproof - plastic sheet - should do, I'd have thought. I've seen stuff that can be slipped in under the bottom row to collect what the felt has not quite managed to do.

But, I'm stumped. 

I think best to wait until you do finally get someone else out to look. It's not going to cause a significant issue unless it gets much worse or goes on for months. Chances are it'll dry up as the weather becomes less extreme-rain, which it does appear to be doing - phew.

It's your call. I certainly wouldn't fork out any money to the current roofer, certainly UNLESS he can clearly answer the three Qs I mentioned above.

Not sure if it's already been mentioned, but has the routing of the TV aerial cables been checked?  It's pretty much in the right place for the leak.  Perhaps the recent torrential downpours with high winds caused an unusual rainwater flow situation there.
